The improved n'lolding machine consists of the outer plates or "moldsections 5 and 6', and the inner plate or sections 7 and 8,'said platesbeing constructed of wood, metal or other suitable material and made insuitable lengths so as to permitthe same to be conveniently handled;

The outer and inner plates are spaced apart to form molding chambers 9for the 9; reception of cement, concretefor otherplas- Qtic materiahtlge plates 7 and-8 being also spaced apart so as to form anintermediate chamber 10 preferably extending throughout the entireheight and length of the wall, as shown. The outer mold tions '5 and 6are reinforced by spaced lo gitudi- I nal angle irons l lto which aresecured con-- nectin bars 12 having elongated' slots 13 forms thereinfor the reception of bolts, or 106 'other-suitablefastening devices 14.

Secured to the connecting bars' 12 by means of the bolts 14 and hearingagainst the adjacent vertical edges of the outer mold sections aremclinedlblocks 15 provided with lateral-guide flange; 16'andhetweenwhich inserted a wedge orflcon'necting strip j1f[, a

tions 25 and 26 extending laterally from the -from. which is suspended aplumb bob so that the operator may see at a glance if the lained inposition on the wall by means of a her 36 are oppositely disposed rodsor stand-- the latter being provided with depending hooks 18 whichengage suitable openings 19 formed in the flanges of the connecting bars12, as shown.

Associated with the outer mold sections 5 and 6 are laterally adjustablee'nd sections or walls 20 and 21 to which are secured suitable hingedplates 22 having elongated slots 23 formed therein for the reception ofbolts, or suitable fastening devices- 24 whereby the end sections orwalls of the mold may be swung laterally and locked in adjusted ositionto permit the formation of .angu ar corners.

As a means for forming the chimney of the wall there is provided aplurality of over-lapping angularly disposed mold sec outer mold section5 and forming a molding chamber 27- which communicates with the moldingchamber 9, as shown, there being suitable plates 28 bearing againsttheangular mold sections so as to permit said sections to be adjustedlaterally'without allowing the cement or concrete to escape from themolding compartment.

W hen it is desired to form the walls of the chimney with a verticalair-space to prevent over-heating of the same, suitable auxiliary moldsections 29 are embedded in the Walls of the chininey and like-wise acentral core 30 for forming the chimney flue, these parts being detachedor removed in the usual manner after the cement or concrete has set.-The angular mold secti-ons'25 and 26 are clamped in assembled positionby means of suitable rods 31 pivoted at 32 of the outer mold section 5,and connecting the free ends of said rod is an angular bar 32 adjustablysecured to the rod 31 by suitable clamps 33.

In order to aline the several mold sections with the finished portion ofthe wall one of said sections is provided with an arm 34 wall is out ofalinement and quickly rectify the same. The-several mold sections arere'- clamping member or bar 36 which extends transversely across thewall and is provided with an elongated slot 37 as shown.

Arranged below the bar or clamping memards 38 provided with lateralenlargements 39 defining depending brackets or supports 4U whichbear-against the exterior faces of the finished wall and. serve tosupport-the side plates and (l, as best shown in Fig. 3 of the drawing.The upper ends 10f the standards 38 are secured to the clamping bars 36by means of bolts 40 the threaded ends of which pass through the slots37 for engagement with clamping nuts 40 while the opposite ends of saidbolts are seated in suitable-recesses or notches 39' -formed in sectionsor plates 7 and 8 are also I .ovided with longitudinal reinforcingflanges or angle bars 11 flanges and carried by the bar 36 is a combinedlocking key and elevating member 41. The locking and elevating member 41is provided with an operating handle 42 and is preferably substantiallyelliptical in crossse ction, as best illustrated in Fig. l of thedrawings that by rotating the handle 42 the sides of the member 41 willbearagainst the inwardly extending flanges 43 of the bars 11 and thusforce the inner mold sections or plates laterally in engagement with theadjacent sides of the wall.

The enlargements 39 of the standards are formed with alined openings 39for the reception of a supporting member ll which extends transverselyacross the wall and is preferably wedge shaped, as shown, said member orbar being provided with a pluanges 4-1 which and disposed betweensaidrality of spaced openings or perforations 4L5 for the reception ofthe reduced end 16 of theelevating member 41', and.also.for thereception of suitable pins or bolts 46 which pass through alinedopenings in the enlargements 3) and thereby prevents accidentaldisplacement of the member 11 and the standards 38 during the moldingoperation. The lower edges of the inner and outer mold sections orplates are provided with re ccsses or notches 47 adapted to receive thesupporting member 44, and extending transversely across theair-chaml'ier or space 10 and embedded in the wall 4.8 are suitabletie-men'ibers 4:9, said members being locked in position by engagementwith the lower edges of the inner mold sections, as best illustrated inFig. 3 of the drawings.

As a means for preventing the cement, concrete or other plasticn'iatcrial from entering the air-chamber 10 while filling the moldingcompartments, there is provided a suitable cap 50 the depending flanges51 of which bear against the flanges 43 of the angle bars 11' so thatthe top of the cap will be disposed flush with the adj acent-ends of thei nner mold sections 7 and 8, there being a suitable opening 52 formedin the cap 50 to permitthe passage of the reduced neck of the operatingme, let" 41C,

Slidably mounted 'forlongitudinal movement in the slot 37 of theclamping member 36 are a plurality of bolts 53 each having onesnbstantially Wedgie 1 y .In constructing the end thereof threaded forengagement with a suitable clamping nut 54 and provided atits oppositeend wit a block or an ular arm 55 adapted to bear against an a acentmold section and revent tilting movement of the some. The ocks '55 arepreferabl wedge disposed in horizontal a inement sons toforma-transverserecessor seat in the wall ior' tion of the supporting member44 when t e mold sections are adjusted vertically on the wall .to permitthe formation oa succeeding course in the said wall. By having thesupporting member 44 shaped, as shown, the same may be read removed fromthe wall without danger of cracking or otherwise in- .jurmg the cementor other plastic material formmg the same.

'wall the supporting members 44 are seated in the rooves formed b .theblocks 55 in the up er aceof the coma n etedfwa ll section and t e innerand outer mold sections placed in position on the wall,

as best shown in Fig. 3 of the drawings, after which the clamping memberis extended transversely across the top. of the mold sections and thestandard 38 adjusted longitudinally in en agement with the flan es 11and fastene by the pin 46 and the, olts 40', in the'manner beforestated. The blocks 55 are then adjusted longitudinallyof the clampingmember and forced "l'aterall into engagement with the inner walls 0 theniold sections, thus securin the latter in alinement with the completesection. After the several parts have been thus adjusted the handle 42is rotated which j causes the locking key 41. 'to bear against the atthe central air-chamber.

-(-oncrete and other then exerted on said handle thus lifting theflanges 43 and press the adjacent mold sections laterally againsttheinner faces of the wall The cement, V lastic material is then shoveledor otherwise introduced into the molding compartment between the innerand outer wall sections and thoroughly tamped ih any suitable manner.Attention is here called to the fact that the cap 50 forms ac osure forthe air-chamber while the nuts 4 '5 and 54 form housings for the upperen of the bolts 40' and 53 thus protecting 'sai bolts from the cementwhile the mold is betng filled. After the cement has thoroughly set, thehandle 42 is rotated in the op0site direction which releases the inner vd sections 7 and 8 An upward pull is clamping member, carrying thestandards 38 and s acing blocks 55 so as to permit the rel of theseveral moldsections. In order to form a succeeding course the.tie-rods49 are placed across the air-chamber at the top of the completed wallsection and embedded in the cement after whichthe supporting member 44is placed in the se'at or grooves formed by the blocks 5 5 and theseveralmold sections adjusted on the wall and secured in 1 positionbythe clamping member, in the manner before describ In Fig. 8 of thedrawingsthere is illustrated a modified form of the invention in whichthe blocks or arms 55 are dispensed with, the bolts 56 being providedwith flattening extensions 57 which bear against the interior walls ofthe mold sections, as shown. In Fig. 9 of the drawingsthe several moldsections or plates are supported in spaced relation by transverse bars58 provi ed vertically disposed pins 59 which bear against this oppositeside walls of the mold sections and thus prevent accidental dis lacementof the same. In this form ofthe evice with the pivoted end walls 60 arelocked in adjusted position by a suitabl'e hasp .61 which engages astaple or eye 62, there being a looking rod or pin 63' threaded throughthe star le 62 for retaining the ad'a'c'ent outer mo d section and endwall in a justed position.

y In Fig. 10 there is illustrated a modified form of clamping member,the latterbein preferably constructed in three sections 6 65 and 66pivoted together as indicated at 67. In this form of' the device thewedge shaped supporting bar 44' is provided with a' p nralityof'transverse openings 68 at each end thereof, the lower end ofthe bar64 being pivotally secured to the adjacent end of the sup orting memberwhile the lower end oftthe ar- 66 is clamped to the opposite end of thebar 44 in any suitable manner,

as by a bolt 69. In'relea sing the side sec,

tions 5' and 6' of the mold the bolt 69 may disposed arms? 3 t'oone ofwhich is pivotally comiected an operatin handle 74 provided with aroller 7 5 where y when the free end 'be detached and the lever 66 swungu of the handle is depressed the roller will engage the adjacent-arm 73and force the clamping members inengagement with the mold sections 5and-6".

-As a means for retaining the tie rods 49 and side plates 5 and 6 inposition, on the vwall during the formation of a succeeding coursewithout the-litfiployment of the su porting bar 44,- the truc'ture shownin 12 is employed in which the clamping mesd l her 7-6 is provided witha pair of dependin arms 77 the terminals of which are reduce and engagesuitable openings 7 8 formed in the tie-rod, as shown. In this form ofthe device 'the side sections of the moldare clamped in engagement withthewall by means of .ver

.tical rods or standards 79 pivotally con- I nected at 80 to atransverse bar 81 and hav ing their u per ends secured-to a similar-bar82 dis ose in spaced relation with the bar 81 an provided with aplurality of openings 83 whereby the standard 79 may be tilted laterallyon the pivotal oints 80 and locked in tilted positio; by suitableelamping bolts 84 engaging the upper ends of the standard 79 and passingthrough the openings 83, as show In Fig. 13 the standard 38' is providedclamping member and the adjacent face of the standard thereby to forcethe standard in engageinentwith the adjacent mold-section, the standard38 being secured in adjusted position on the member by a bolt 89 passingthrough one of a plurality of openings 90 formed in the clamping memberin the form'of the device, shown in Fig. 16 of the drawings. l

A further modification is illustrated in Fig. 17 of the drawings inwhich the standards are formed in two sections 91 and 92 each providedwith. a laterally extending arm 93 between which is mounted for slidingmovement the wedge shaped supporting member 44.' The extensions 93 areprovided with transverse perforations 94 and are embraced by a sleeveorcollar 95 also provided with perforations, as shown, so that by movingthe extensions laterally and passing suitable bolts through saidperforations the standards may be adjusted to fit walls of differentthicknesses. 1
